SA1 opening cutscene
I'm not sure what relevance the "number of polygons" has with regards to the opening cutscene. Assuming you mean the intro video that appears after the "Sonic Team" screen, that's prerendered; it's literally playing a video file from the disc. No polygons to render; that was all done during development. ---GerbilSoft (talk) 16:34, 6 October 2016 (CDT)
